The 75-kg man pushes on the 150-kg crate with a horizontal force F. The coefficients of static and kinetic friction between the crate and the surface are μs = 0.3 and μk = 0.1, and the coefficient of static friction between the man's shoes and the surface is μ′s = 0.8. What is the greatest acceleration the man can give the crate if the man's acceleration is zero at this instant? I keep getting 1.96 but it says answer is...

Work on a sliding crate. A worker pushes a 47.0 Kg crate across a level horizontal floor by applying a constant force of exactly 150.0 N at an angle of 23.0 degrees below the horizontal. The crate begins at rest and ends 15.0m from where it started traveling at 2.6m/s A. What is the work done by the applied force as the crate moves across the floor? B What is the work done by the friction force as the crate...

Two workers are sliding a 300 kg crate across the floor. One worker pushes forward on the crate with a force of 380 N while the other worker pull in the same direction with a force of 350 N using a rope. Both forces are horizontal and the crate slides at a constant speed. What is the crate’s coefficient of kinetic friction on the floor?

A factory worker pushes a 26.5-kg crate a distance of 4.3 m along a level floor at constant velocity by pushing horizontally on it. The coefficient of kinetic friction between the crate and the floor is 0.27 Suppose the worker pushes downward at and angle of 340 below horizontal. (a) What magnitude of force must the worker apply? (b) How much work is done on the crate by this force? (c) How much work...

Just asking help with Part I
A factory worker pushes a 30.0 kg crate a distance of 4.40 m along a level floor by pushing downward at an angle of 28.0° below the horizontal. The coefficient of kinetic friction between the crate and floor is 0.260. The Crate is Pushed with Increasing Speed Now assume that, instead of the previous situation, the worker pushes harder (without changing the direction of his push), so that the crate moves with increasing speed....
